19 Aug 2003 | Subject: | Strongly Correlated Electrons | cond-mat.str-el | Abstract: | We study the effect of impurity pinning on a one-dimensional half-filled electron system, which is expressed in terms of a phase Hamiltonian with the charge degree of freedom. Within the classical treatment, the pinned state is examined numerically. The Mott glass, which has been pointed out by Orignac et al. [Phys. Rev. Lett 83 (1999) 2378], appears in the intermediate region where the impurity potential competes with the commensurate potential. Such a state is verified by calculating the soliton formation energy, the local restoring force around the pinned state and the optical conductivity. | Source: | arXiv, cond-mat/0308364 | Services: | Forum | Review | PDF | Favorites |
